CAR-ROOF.

To all 10710112 1'! may concern Be it known that I, THOMAS LATHAN RUssEnL, a citizen of the United States, re-

siding in Chi ago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in C air-Roots, of which the following is a specification.

My invention relates to car-roofs of the outside metal type and has for an objectthe providing of an outside metal roof construction in which the roof-sheets shall be retained along their ridge-ends by a cap that makes interlocking engagementwith them and yet permits them freedom of bodily movement; and the invention has for other objects such other ad. 'antages and results as may be found to obtain in the structures hereinafter set forth and claimed.-

In the accompanying drawings. forming part of this specification, and showing for purposes of illustration a preferred embodiment of the subject matter hereinafter claimed,

eaves construction similar to the view given in Fig. at but showing a modified form adapted to a roof-frame in whicli' there is a wooden side-plate instead of the angle sideplate shown in Fig. i.

Like reference numerals parts in all the drawings.

20, 20 are the roof-sheets, each of which has an under-bent hooked flange 21 along its eaves-end and an upstanding inwardly rebent flange 22 along each of its sides, and has along its ridge-end a flange 23 that is upwardly bent and inwardly rebent and shouldered. the free edge 2-1 of the shouldered portion 25 extending inward over the These roof-sheets are indicate like ridge of the roof and occupy the spaces between the transverse mullions 26 that are nailed on the top of the wooden roof-sheathing :27 at intervals along the roof; the inter- 'als between the successive mullions being somewhat greater than the overall width of the said roof-sheets that occupy the spaces between these mullions, so that each roofsheet has some free-space for movementlaterally between the mullions on eitherside of it. Along the ridge, between the mullions, there are ridge-caps 28 that are of inverted channel form with outwardly extending and inwardly rebent flanges 29 along each edge of the channel 30. The channel 30 of said ridge-caps overlies and engages the faces of the aforesaid shoulders 25, and the rebent edge-flanges 29. of the ridge-caps, are hooked freely over the aforesaid extended free edges 24 of the shouldered portion of the roof-sheet flanging. This manner of interlocking and engagement of the ridgecap with the ridge-flanges of the roof-sheets retains the roof-sheets from displacen'ient from theeaves of the roof and yet permits them freedom of movement both laterally and toward. the ridge-line of the roof. Additionallyto secure the roof-sheets from 'any possible disengagement from their interlocking with the ridge caps, a lock-strip 31-11 simple. loose strip of woodmay he slipped in under the ridge-cap and between the ridge-fiz-mges of the roofsheets before the ridge-caps are finally secured in position. The ends of the ridge-caps are secured in position by the corner-caps which are doubly shouldered to conform with and fit over the outside of the ridge-cap ends and pending lateral flanges that considerably overhang the sides of the mullions and are inwardly rebent so that they may be tele scoped into and loosely engage with the aforesaid upstanding side-flanges 22 of the roof-sheets, allowing free movement of said roof-sheets toward and away from the, mullions. The eaves-ends of the mullions overhang the recess 27 that is rabbeted out along the top of the eaves portion of the roof-sheathing; and the eaves-end 3lof each mullion cap is bent downward and rebent inward to cover the eaves-ends of the engagement between the mullion-cap flanges and roof-sheet flanges and to hook under and engage the said overhanging eaves-end of the mullion. The mullion-caps are secured near the ridge by the nails that are driven through the mullions, mullion caps and roof-sheathing and into wooden ridge'pole sections 36 that span the space from carline to carline and are secured by the underneath "ridge-plate 37' that extends underall the carlines. The running-board saddles 38 rest on top of the corner-caps 32 and the mullions and their caps, and each saddle is secured by the bolt 39 passing down through it and through the cornercap, mullions, sheathing, ridge-pole and underneath ridge-plate 37. Over the top of the bolt 39 a small water-proofing metal cap 40 is let into the recess in the top of the running-board saddle to prevent seepage of water into the bolt-hole. It may be noted that the carlines are fewer in number than the mullion-divided spaces along the top of the roof, and therefore do not directly underlie the mullions, with the possible exception of the carline at the middle of the length of the roof. Each carline 41 is U- shapedand extends from side to side of the car, and in its channel there is a wooden filler; andso where the carline underlies the mullions at the middleof the length of the car the beforementioned nails 35 would. enter the said wooden filler of the carline and the. said bolt 39 would pass through such wooden filler and the bottom of the channel of the carline and then through the underneath ridge-plate 37 The rebent eaves-flanges 21 of the roofsheets are loosely engaged by the hookstrips42 that occupy the aforesaid recess along the eaves portion of the roof-sheath-' ing and are secured well within the eaves edge of said sheathing; These hook-strips extend along the entire length of the said eavesrecess and are made in sections that lap end for end. Overlying the under portion of these hook-strips and extending in between said portion and the rebent roofsheetflange 2-1 that is engaged under the upper )ortion of the hook-strips there is an eavesashing 43, the inner end of which is flanged diagonally upward, #at 44, and the outer portion of which is bent downward over the outside of the car and has hanging mullion-end and extending down through the outwardly projecting upper member of the metallic angle side-plate 46.

And in the modified form of structure shown in Fig. 12 the hook-strips are secured by the nails 47 driven through the hook-strip and roof-sheathing and into the wooden side-plate a8, and the 'fiashings are secured in their depending portion by the nails 19 driven through the side-sheathing 50 and into the said wooden side-plate.

From the foregoing description and from inspection of the drawings, it willbe noted that the roof-sheets are freely floating, being free to shift bodily in all directions, and yet have all of their edges locked from displacement, each edge being provided with a flange that interlocks freelywithin a reversely formed flange of an adjacent roofmember. Such interlocking is effected with ,the hook-strips along the eaves-ends of the roof-sheets, and with the flanged mullioncaps along their sides, and with the ridgecaps along their ridge-ends. The entire sheet, although locked from displacement, has essential freedom of movement bodily from side to side between the mullions and toward and awayrfrom the ridge-line and eaves of the roof of the car; and yet the ridge-caps, engaging .the shoulders of the. ridgeend flanges of the roof-sheets, prevent the sheets from being displaced too far to-' ward the eaves of the roof. It will further be noted that the retaining means along the eaves-ends of the roof-sheets and such eaves-' ends of the sheets themselves are secured well within the eaves-edge of the roof, and

nothing overhangs said edge except the eaves-flashings that are independent of both the roof-sheets and their retaining hookstrips so that a side-wipingaccident that may damage or rip away these eaves-flashthe roof-sheets or their retaining hookstrips. Other advantages will be apparent from the description and drawings.

- The invention may be embodied in forms ings will neither damage nor detach either p of construction other than the specific form that has been shown and described for purposes of illustration, and still be within the scope and subject matter of the claims hereinafter made. Y
